=This invention relates to a new or improved childs folding push-chair and has for its object the provision of a push-chair,ipartsof which are constituted'by the body andlid'of an attache case '5 so that the components of the push-chair (that is; the wheels, the foot and arm rests and if de sired the handle also) maybe folded so as to be accommodated completely within the attache caseqwhen closed. Acharacteristic feature of engage one with another when erected to form arigid structure.

Broadly, the invention provides a childs fold ing push-chair wherein the main framework of the chair is normally accommodated within an attach case and has pivotally connected thereto sub-structures carrying front and rear wheels which are adapted when'the open attachrcase is inverted to drop out of the case interior into the working position. Means may be provided for automatically lockingthe wheels in the working position. The lid of the attache case inwhich the main framework is accommodated is, constructed for use as a footrest. The chair is provided with folding armrests normally accoInmo-. dated Within the attach case lid and adap'ted'to be swung intothe position of use alongside the inverted case body, and with a footrest pivotally mounted on the front wheel substructure. The handle for pushing the chair during use may be foldable so as to be housed with the attach case lid when the chair is folded or may be attached to the lid exterior for use when pushing the chair Figure 4 is a transverse sectional View on line IV, IV, Figure 3, and

Figures 5, 6 and 7 are side, front and plan views respectively of a device for locking "the unfolded wheel sub-structure in the working position.

In the embodiment illustrated a main metal frame work i, which is, substantially square in plan, is mounted Within the body 2 of an attach case, the frame I having four outwardly extending legs 3 3 arranged in front andrear of two substantially U-shaped members 5% ;5",

each of which carried at opposite ends ofthe flat base 6*, 6'" of theU a rubber tyredm heelf 1 Prof suitable, size. The U-members 5 ,5? i havecranked or. bent limbs 4 to fac htate" accommodation] thereof, together withltheir 71169181 within the body 2 of the'attach case (see especially Figurea3). The rear wheel U-member 5 is adaptedto be folded into the case 2 first,-with the front wheel U-m'emb'erie above it in order toallowa footrestt, pivotally carried by the front wheeljU-memberj ,be housed; w e fol w h n-j the ce bodrl 2, Upon each of the legs-3 3 of the mainframe l is slidablymounted a flattened collar 9, which, when the case is in the inverted position, drops down along the leg 3*? or 3 so as to engage with 2. lug Iii provided on the limb 4 or 4 of the U-member 5 5 pivoted thereto in order. to lock same in the working position. This looking action is effected automatically when the case isinverted, the collar 9 dropping by rav- 1 ity into the locking position, Straps ll limit the outward swinging movements of limbs 4 i -When, after use, the attachcase 2 is re-,

stored to its normal position (seeFigures 3 and 4) the U-member locking collars- 9 drop out of l the locking position" by gravity, allowing the'said u -memberj 5 or 5* to be folded intothe case ine Somewhat similar l3 of the attach' case is hingedly connected to theca'se body 2.. The hinges ,I4

are not, however, directlyc'onnected. to the case body 2, near to the upper edge thereof, butare provided. with long links l5 which are pivotalabout half-way down the depth thereof. These links l5 allow the hinged lid I3 to ,be used forl closing the case and also enable the said-lid to be swung back so that the hingecarrying edge- It thereof is substantially level with the floor I! of thecase'body 2. Hence, when :the latter.

is inverted to allow the body'fioor I! to beused as a seat (Figures 1 and 2), the swung-back lid I 3 of the case constitutes a back rest. To relieve the actual case floor of thechilds weight a sheet-0f plywood (not shown) mayline the inside face of the floor and be mounted on the metal frame housedltherein. The swung-back lid 13 is held in the position in which it con- 40 ly attached tothe case body ata position I5 I stitutes a back-rest by means of a pair of arms l8 which are pivoted to brackets I 9 within the lid 13 and adapted to be swung outwardly and sidewardly to take up positions at opposite sides of the inverted case body 2. The outer extremities of the arms l8 pass through openings inthe walls of the case body 2 and enter slots 20 provided in the metal frame l therewithin so as to connect the arms I8, and with them the lid I 3 rigidly to the mainbody frame I. An in verted U-shaped handle 2| is mounted on the outer faces of the flanges 0f thelid' l3 and serves for pushing the erected chair, and for carrying the closed case.

1. A folding childs push chair comprising an inverted attache case body open at one end and a lid pivotally secured to said body for covering the open end thereof, a main frame mounted in the body, independent front and rear substructures carrying pairs'of front and'rear supporting wheels pivotally connected to said main frame adapted to be raised vertically into said case body, and arm supporting means pivotally connected to said lid, adapted to be folded thereinto, said frame and arm supportingmeans in-- cluding locking means adapted to interlock said lid and arm rests in predetermined position.

'2. A folding childs push chair comprising an inverted attache case embodyinga body, a lid for said body and links connecting said body and lid with each other, a main frame mounted in the body of said case, independent front and rear wheels carrying substructures extending downwardly fromsaid main frame and pivotally connected therewith topermit said structures to be vertically raised into the case body, arm supporting means pivotally connected to said lid for folding said supporting means into said lid and interlocking means on said arm supporting means and said main frame for interlocking said main frame with said lid when the latter is in substantially upright position.

3. A folding childs push chair comprising an inverted attache case including a body a lid connected to each other, a frame mounted in said body, independent wheel supporting substructures pivotally connected to said frame adapted to be raised vertically into said body, arm rests pivotally connected to the interior of said lid adapted to be folded into said lid and to a position alongside of the case body, said case body including openings and the lower extremities of the arm rest embodying offset portions adapted to be extended through said openings and interlocked with the frame in said body to directly transmit stresses on said lid to said frame.

fl. A folding childs push chair comprising a attache case including a body having a lid hinged thereto, a main frame mounted in the body of said case including symmetrically arranged limbs, front and rear substructures each including a U-frame pivotally connected to said limbs and gravity actuated locking means consisting of collars slidably, embracing the limbs on the main frame and projections on said U-frames laterally engaging said collars when looking said U-frames in proper working position.
